Abstract
The method for controlling a motor driving a load holds the speed of the output shaft of the motor substantially constant as the torque imposed upon the shaft by the load varies, then regulates the rate of change of the output torque delivered by the motor's output shaft based on the sensed value of output torque as the motor's speed decreases.
